GnRH-dependent precocious puberty

GnRH-dependent precocious puberty happens when the brain activates the usual puberty pathway earlier than expected. The pituitary then signals the ovaries or testes to make sex hormones, leading to progressive pubertal changes. Treatment may use a GnRH agonist to quiet this signal for a time.

This form is sometimes called central precocious puberty. It follows the same sequence as typical puberty, but the timing is early. A clinician looks for a pattern that is advancing rather than a single isolated sign. Assessment can include growth measurements, examination, bone maturity, and hormone tests; a female hormone blood panel may be relevant for some children. The reason for early activation is not always found, and the specialist decides whether further evaluation is needed.

Attend the planned endocrine reviews and bring notes about growth, body changes, periods or genital changes, headaches, and emotional wellbeing. Ask the team to explain the proposed medicine, dose timing, expected physical response, and monitoring plan. Keep medication records accurate, especially around school trips or holidays. Give the child privacy and reassurance; early development can feel confusing even when the child feels physically well.

Seek urgent help for a seizure, fainting, breathing difficulty, facial or throat swelling, or a severe headache accompanied by vomiting or vision problems. Contact the specialist about a persistent headache, a new neurological symptom, unexpected bleeding, or pubertal progression despite treatment. These signs do not identify a cause by themselves, but they should be assessed without waiting for a routine visit.

Ask how the team established that the central pathway is active, whether additional tests are appropriate, and what treatment aims to change. Discuss the review interval, injection care, missed-dose instructions, school considerations, and how the team will decide when treatment should finish.
